#   AX_BOOST_THREAD

# DESCRIPTION
 
10
#
 
11
#   Test for Thread library from the Boost C++ libraries. The macro requires
 
12
#   a preceding call to AX_BOOST_BASE. Further documentation is available at
 
13
#   <http://randspringer.de/boost/index.html>.
 
14
#
 
15
#   This macro calls:
 
16
#
 
17
#     AC_SUBST(BOOST_THREAD_LIB)
 
18
#
 
19
#   And sets:
 
20
#
 
21
#     HAVE_BOOST_THREAD
